UNITED STATES PATENT OEEIOE.

To all whom t may concern:

Beit known that I, JOHN R. GREENWOOD, a citizen of the United States, residing at Boothwyn, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Dyeingl-- Machines, cation.`

This invention relates to machines for dyeing, and equally Well adapted for -,warps or piece goods; among its distinguishing features are the repassing of the material to be dyed through the machine in successive par allel` courses, and the separation of the material both vertically and horizontally at each return of the courses, to thereby lessen the liability of its entanglement; also, the positive movement of the material is effected without undue tension upon it (thereby lessening the damage by breakages) by power driven rolls which carry the material and which are positively rotated in unison at uniform surface speeds, Vby an arrangement of means which control their movements in the directions necessary for the successive passing of the material .through the dye until it is evenly and thoroughly colored, which must be done without expressing any dye from the material until its final passage from the machine. The expressing of any dye while the material ispassing from one part of the machine to another part, and at a time when of which the following is-a spec it is exposed to atmospheric'conditions is detrimental to uniform coloring, and in this machine this heretofore defect -has been overcome, most eifectuall'y, by the employment of a pair of final squeeze rolls which express the dye when the work is com pleted and at the time the material passes from the machine to the washery, also the nonpulling of the material through the machine, which insures uniform coloring, as the material is thoroughly dye saturated throughout the process. There is also, in this machine, a saving of a large amount of dye which is returned to the vat by the iinalsqueeze rolls. Where only one pair of squeeze rolls are employed,as in previous machines, and the material must be pulled over non-power driven rolls, the capacity of the machine is limited by the Atensile strength of the material going through the machine, and any bunching of the material, knots, etc when forced through the former single pair of squeeze rolls produces uneven pressure and uneven expressing of the dye, resulting specication of Letters Patent.

in spotting and uneven depth of color. These defects have been overcome vby the power driven lrolls which carry the material along without undue tension, andthe nal ysojueeze rolls which permit fulland free saturation until perfect work is assured.

vflhe illustrations show the machine carl rymg warps, in which Figure 1 1s a side elevation of the `machine with the side of the vat and the driving pul'- ley and Vgears exterior to line :n :c Fig. 3, removed. lFig. 2 is an elevation view of the nal squeeze rolls. of the machine with the vat end removed. Fig. 4 is a top or plan view, with the weights and their levers removed. Fig. 5 is a view Fig. 3 is a front elevation` of a portion of one of the power driven rolls,

, its gear and the removable key which secures the gear to the roll shaft.

' In a vat or tank 1, u on angle irons 2, 3 a framework 4 is removably su ported. Upon theupper horizontal sides o the framework a series of power driven rollers 5 are supported by shafts 6 in bearings 7, the rollers being spaced apart, and `each shaft having a gear 8, and intermediate the gears are pinions 9 supported on studs 10 in bearings 11' secured toI the framework. The gears 5 are secured to shafts 6 by keys 12 or other suitable means which may be removed so that if desired, to insure an even tension upon the warp, should there beany inequality in the diameter of a roll, or rolls, any desired roll or rolls may be free lto be rotated by the contact of the material, instead of being positively driven by the gears.

Beyond the rolls 5 and somewhat above them there is an auxiliary roll 13 at the outer end ofthe machine, with a shaft 14 and bearings 15 and agear 16 engaging the gear 8 of the adjacent roller 5. Bearing 15 has up- Wardly extending bifurcated projections 17 carrying a roller 18 pressing upon the material as it passes over roller 13.

At the inner end of the machine, and above the adjacent roller 5 there is an auxiliary roller 19, with a shaft 20, bearings 21 and a gear 22 engagin a gear 8 of the adjacent roll 5. Mounted a ove the framework' 4 are stands 23 in which are bearin s 24, 25 for shafts 26,27 which support the drawing-in or initial squeeze rollers 28, 29. Upon stands 23 are brackets 30 sup orting a shaft 31 upon which is a driving pu ley 32 and a pinion 33 engaging a gear 34 on shaft 26 of roll 28.

supports 46, 47 secured tofvat 1.

32 there is a sprocket wheel 35 carrying a chain 36 drivin another sprocket wheel 37 on a inion stu 10, and driving apinion 9, .andt is is the means for driving the series of rolls 5, and rollers 13 19, the parts b`eing pro- 39, 40 are driven at a uniform speed. Sprocket `projections engaging the bearings,

wheels and a chain ma equally well be used if desired. Thus all t erollers and the initial or drawing-in and final squeeze or drawing-out' rollers are positively power driven i to` carry the warp ormaterial along Without any tension being produced upon it.

At the lower part of framework 4 there are placed a series of idle rollers 51 on shafts 52 supported in bearings 53. Above gears 5, 16, 22 and pinions 9 there is a shield 54 to prevent the possible entanglement of the material in the ears. -Above the roller 5 adjacent roll l13 t ere are pin guides 55 to deflect the warp to roller 13. Above shield 54 a roller 56 is placed to prevent the sagging of the outgoing material. Above bearings 25 levers 57 are fulcrumed to stands 23 witldi weights 58 are adjustably mounted to press down roll 29 to Give a desired tension to the warp or material, while levers 59 and larger -weiglits 60 are similarly provided for roll 39.

A dripper 61'is placed under roll 38 to return the expressed dye into vat 1.

The courses of the warp through kthe machine are as follows; two warps are shown and their movements are identical, and the number of warps dyed in one o eration being only limited 'by the length of t e rolls. The material iirst enters at 62 andl passes between rollers 28, 29 then at 63 to and be- -tween the drawing-in rollers 13, 18 then at 64 down to and under the roller 51 at the same end'of .the machine, then in successive upward courses 65 and downward courses 66 over a roller 5 and under a roller 51 until passing the last roller 51 it goes .up at 67 and around roller 19 and at 68 horizontally to and between rollers 13, 18 but being deiiected in this movement by guide pins 55 as seen in Fig. 4, to one'side of and parallel to its previous course between rollers 13, 18, this is the first course; the second course is parallel to the first course until the last roller 51 is passed, then the war at 69 passes to and over roller 28, separating the courses of warp or material at 67, 69 at the incoming end of the machine, and also at 63 as it passes to rolls 13, 18, from its previous course 68 tothe same rolls, this is the second course; each alternate course is repeated three times, after which the warp passes at 70 to and betweenl the final or drawing-out rolls 3 39 where it is s ueezed dry, the expressed ye returning to t e vat, which saves much dye, and facilitates the washing of the material, as there is less dye to be removed.
